- 内燃機関のための排ガス後処理装置(10)であって、
排ガスが貫流するハウジング(11)、
該ハウジング(11)内に形成されており、排ガス浄化のために触媒(16、17、18)及び/又は 粒子フィルターを収容する排ガス浄化室(13、14、15)、
前記ハウジング(11)内に形成されており、消音のために貫流方向において所与の奥行を有するマフラー室(19、20、21、22、23、24)、
を有する、排ガス後処理装置において、
前記排ガス浄化室(13、14、15)の各々は、2つの前記マフラー室(19、20、21、22、23、24)の間に前記排ガスの流れの方向に沿って配置されており、且つ下流に配置された前記排ガス浄化室と部分的に重なっており、
前記マフラー室の奥行は、減衰させる排ガス騒音の波長の4分の1(λ/4)に相当しており、前記ハウジング(11)を貫流する排ガス流(25)はN個の排ガス部分流(25a、25b、25c)に分けることができ、これら排ガス部分流はそれぞれ、前記排ガス部分流(25a、25b、25c)のそれぞれにとって個別の、少なくとも一つの排ガス浄化室(13、14、15)、及び前記排ガス部分流(25a、25b、25c)のそれぞれにとって個別の、少なくとも一つのマフラー室(19、20、21、22、23、24)を貫流することを特徴とする、排ガス後処理装置。 - 前記排ガス部分流(25a、25b、25c)は、前記排ガス浄化室(13、14、)及びマフラー室(19、20、21、22、23、24)を貫流した後に合流して排ガス流(25)とすることができることを特徴とする、請求項1に記載の排ガス後処理装置。
